This study investigates the main factors influencing the acceptance and adoption of voice-driven systems. To this end, the Technology Acceptance Model was extended by incorporating the concepts of perceived security, perceived response quality, and perceived comprehensibility of the system. Our model is validated with a path analysis using the SEM module in JASP. Data were gathered through a standardized paper-and-pencil survey from 146 respondents, all under 35 years old and owners of voice-enabled devices. Findings reveal that perceived comprehensibility of the system enhances the perceived ease of use of voice-driven system. Furthermore, perceived response quality, perceived security, and perceived ease of use positively affect the perceived usefulness of voice-driven systems. No support was found for a positive effect of perceived security on the intention to use voice-driven systems.
